Generally, a download manager enables downloading of large files or multiples files in one session.Many web browsers, such as Internet Explorer 9, include a download manager.Stand-alone download managers also are available, including the Microsoft Download Manager.

if you do not have a download manager installed, and still want to download the file(s) you've chosen, please note:

You may not be able to download multiple files at the same time.In this case, you will have to download the files individually.(You would have the opportunity to download individual files on the "Thank you for downloading" page after completing your download.)

Files larger than 1 GB may take much longer to download and might not download correctly.

You might not be able to pause the active downloads or resume downloads that have failed.

The Microsoft Download Manager solves these potential problems.It gives you the ability to download multiple files at one time and download large files quickly and reliably.It also allows you to suspend active downloads and resume downloads that have failed.

To help ensure that links between documents work correctly, store all the PDF files in the documentation set in the same directory. If you download additional standards support or protocol documents by Microsoft, you should store those files in that directory too.

The self-extracting Exchange_Standards.zip file contains all the specification and companion overview and reference documents that are included in the documentation set. The [[ReadmefirstExStand]].pdf file in the .zip file contains late-breaking information about the documentation.

The Microsoft Exchange and Microsoft Outlook standards documentation is intended for use in conjunction with publicly available standard specifications and network programming art, and assumes that the reader either is familiar with the aforementioned material or has immediate access to it.

The technical documentation provides information that is useful to the following audiences:

Implementers: Sufficient conceptual and reference information for a successful implementation of one or more protocol specifications for a given task or scenario.

Reviewers: A definitive resource for readers who want to evaluate or understand support for one or more protocols.
